About this study

Comparative effects of sprint interval training and continuous aerobic conditioning on running economy, endurance and fatigue resistance in runners

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age typically between 18 and 30 years old.
  • Participants are in good health and had no severe injuries during the last six months before the study
  • Non-smoker
  • Individual free from cardiovascular, metabolic disease

Exclusion criteria

  • Presence of any musculoskeletal injury or illness
  • Runners with irregular training schedules or inconsistent performance.
  • Use of medications that could impact exercise performance or safety.
  • Inability to commit to the training program or testing schedule.

Treatment and study plan

Sprint Interval Training

Other

13 participants will be in sprint interval training group, who will only perform repeated sprint exercise. 30m-all out sprint with repetitions

Continuous aerobic conditioning

Other

13 participants will be in continuous aerobic conditioning training group, who will only perform aerobic exercise. running along with increase duration.

Primary outcomes

  1. Repeated sprint

    Time frame: 6 weeks

    The Repeated Sprint Test consists of a sequence of maximal sprints (usually 6 to 10 sprints) over a distance of 20 to 40 meters, separated by 20 to 30 seconds of either passive or active recovery

  2. Time to exhaustion test

    Time frame: 6 weeks

    A Time to Exhaustion (TTE) test measures fatigue by determining how long an individual can sustain a specific workload (e.g., power output or speed) before becoming unable to continue

  3. 6-minute submaximal run test:

    Time frame: 6 weeks

    A 6-minute submaximal run test on a typical 400-meter outdoor track at a steady speed was used to estimate running economy.

  4. Cooper vo2 max Test

    Time frame: 6 weeks

    The Cooper Test is a 12-minute run test used to measure a person's aerobic endurance and estimate their cardiovascular fitness, specifically their VO₂ max
